A system and method for removing debris from solar modules in a solar module array. The system includes an air supply for providing pressurized air to a debris removal wing, a support art configured to support the debris removal wing proximate a solar module, and a support base fixing the support arm to a vehicle, the vehicle operable to advance the debris removal wing along the solar module array. The debris removal wing includes a first air outlet for directed pressurized air to remove debris from the solar modules. The debris removal wing may include a second air outlet for directing pressurized air to at least partly hovering the debris removal wing proximate the solar modules.

An apparatus, method and system for cleaning a solar panel includes a solar panel, one or more fluid reservoirs, a fluid dispenser at a first side of a solar panel, a mechanism for providing pressurized fluid to the fluid dispenser from the fluid reservoir(s), and a mechanism for dispensing the fluid from the dispenser. The solar panel is periodically cleaned and the motivation for cleaning may be a detected output condition of the panel, a detected weather condition, an expired time condition, detected precipitant accumulation, a manual command, or the like. The fluid(s) may include a gas and/or one or more liquids. A heater may be provided to heat the fluid(s).

A solar panel comprises a double-glass photovoltaic module mounted in a frame. The double-glass photovoltaic module comprises a plurality of solar cells embedded between a front glass sheet and a rear glass sheet. The rear glass sheet exhibits a larger extension than the front glass sheet, in at least two spatial directions, as measured in the rear glass sheet plane. The frame comprises a clamping element clamping only the rear glass sheet and not the front glass sheet of the double-glass photovoltaic module. The front glass sheet is either flush with a plane defined by inner edges of a front face of the frame or protrudes beyond the front face of the frame.
